700 X 1,024 = 716,800 MB>KB
716,800 - 3072 = 713,728 File System Overhead
713728 / 20 = 35,686.4 ~ 35,686

SpaceKalk Plugin for Nero

ud store 35000 files

=======================================
I want to resize and crop some, and put them back on this disk
..Once I have a picture resized etc. and attempt to save it back to that disk
..Pop-ups tell me ..."JPG save error cant open file for writing: [file name]"
...What's this about?
how can I get around it?
---- ----- ---
I have also tried saving a cropped, resized pic in bitmap format to this disk.
...Pop-up tells me the disk is full ..
Lable says disk capacity:: 700MB
This disk now has a total of 14 pictures on it which when totaled up together amounts to only 2500KB
--- ----- ---
....How can disk be full with so little on it?
....what the heck is goin on anyhoo????

If the CD-R has been "Finalised" then no further data can be written to it. Its not like a Hard Drive, a normal CD-R can only be written to, not erased.

If the CD has not been finalised, you can write another "session". Doing so will cause a significant loss of space each time, as all tables of contents are re-written in the space available, as are the changed files.

The sessions may not all be visible until the session is closed.

Its not the way CD-R are meant to be used, you should only burn them when editing is complete. Until then keep them on the HDD.

CD-RW disks can be erased and re-recorded, but its also a messy operation, and they are not always readable on all drives.
